BOILER-FEED-W'ATER REGULATOR.

T 0 all whom it may concern Be it known that l, VVILLIAM E. Guise, a citizen of the United titates, residing at Rittman, in the county of Wayne and State of Ohio, have invented certain new and useful Improvements in Boiler-Feed-lVater Regulators. of which the following is a specification.

This invention has for its object to provide an improved automatic regulator for the water feed valve of a steam boiler in which the feed or supply valve is automatically opened when the quantity of water in the boiler becomes dangerously low by the pressure of the water acting directly upon the valve, assisted by adequate spring means thus permitting the water to flow into the boiler.

Another object is the provision of a regulator of this character in which the feed valve is automatically returned to closed position after the water in the boiler has been brought up to normal level, by admission of steam to a cylinder receiving a pistonwhich is connected with the feed valve to actuate the latter.

A still further object resides in the pro vision of a steam valve controlling the ad mission of steam to the cylinder of the valve operating piston which is controlled directly by a float arranged to float upon the surface of the water in the boiler.

With these and other objects in view as will appear as the description proceeds the invention comprises the novel features of construction, combination of elements and arrangement of parts which will be more fully described in the following specification and set forth with particularity in the claims appended hereto.

Figure 1 represents a longitudinal sectional view through the improved regulator.

Fig. 2 represents a perspective of the water feed valve removed from the case.

Fig. 3 represents a perspective of the bushing which is arranged internally of the valve case.

Fig. 4 is a detail sectional view showing a modification in the arrangement of the steam valve.

Referring to the drawing in detail, wherein similar reference numerals designate parts throughout the several views, the numeral 5 indicates a cylindrical valve case or housing having a closed lower terminal in. which is formed a drain port 6 and provided with an open terminal receiving a removable cap 7.

Specification of Letters Patent.

1919. Serial No. 311,476.

An inlet port 8 is former. at one point in the side wall of the case 5 and at its diametrically opposite point superposed outlet ports 9 and 1.0 are formed therein, the port 9 being of relatively small diameter and normally open so as to normally admit a predetermined quantity of water to flow into the steam boiler. A bushing 11 is fitted in the bore of the valve case 5 and is formed with ports 8*, 9 and 1O" which register with the ports 8, 9 and 10 in the valve case 5. The upper terminal of the bushing is flanged as at 12 and is anchored in a seat formed in the valve case 5 beneath the demountable cap 7 being held seated by said cap.

A hollow cylindrical valve 13 having a closed upper terminal 14 and an open lower terminal is mounted for vertical reciprocation in the bushing 1110f the valve case and is provided at one side with a relatively long opening or port 15 which permanently registers with the inlet port 8 of the valve case admitting water to the interior of the vliir drical valve at all times. The side of the valve 18 opposite the port 15 is formed with relatively small and large longitudinally spaced ports 16 and 17 adapted for alternate registration with the ports 9 and 10 whereby the water contained in the valve is permitted to alternately flow into the ports 9 and 10, according to the position of the valve. As stated, the relatively small port 9 is normally covered by registration of the relatively small port 16 in the valve therewith but when the water supply in the boiler becomes below normal the valve 13 is elevated so as to move the relatively large port 17 thereof into registration with the port 10 so as to admit a greater quantity of water to the boiler and thus bring the water level up therein.

A stem 18 is fastened to the closed top 14 of the valve, extends through the cap 7 and is pivotally connected with one terminal of a rocker arm 19 pivotally supported in a post 20 secured upon the cap 7 and having pivotal connection at its opposite terminal with the stem 21 of a piston 22.

The piston 22 is reciprocably mounted in the cylinder 23 adequately supported upon the valve cap 7 and having connection with the interior of a steam valve case 24 by a steam pipe 25 which latter communicates with the lower portion of the cylinder 23 so as to admit steam thereto below the piston 22. The upper portion of the cylinder 23 Patented July 5, 1921.

is formed with a vent preventing back pressure above the piston 22 and an expans on coiled spring 26 is confined between'the piston and the upper part ofthe cylinder so as to normally tend to depress the cylinder and thus elevate the valve 13 through its connection with the piston the rocker slidably mounted 'lower terminal or the steam pipe 25'with the valve case 24, the
